To all whqmit may concern/:

Be it known that. I, J ACOB G. EICHOLTZ, a-

I citizen of the vUnitedStat-es, residing at Ida Machine, of

Grove, in the county of Ida and State of Iowa, have invented a new and useful Harness which the following is a specification.

My "invention relates to-sewing-machines, andparticularly to a harness-machine for sewing and repairing harness and other articles of leather and equivalent heavy material,

'the object in view being to provide in connection with. a harness vise or clamp'in proved means for reciprocating a needle transversely of the jaws of said vise or clamp, to; gether with means forfeeding the needle in a direction parallel with the jaws in a step- -ciprcate in a direction perpendicular to the faces of the jaws of the vise or,c1anip or may .vide a simple and efficient construction of be arranged toreciprocate obliquely with relation thereto.

A further object of theinvention is to prothread-tension and means for varying the point of release thereof.

- Further objects and advantages of this invention will appear in the following description,.and the novel features thereof will beparticularly pointed out in the' appended' claims.

responding parts inall the figures oflthe drawings;

tial feat' e of my invention is illustrated in or clamp having a fixed member 1, carrying a fixed jaw 2 and a movable jaw 3, pivoted,

as at 4, to a forwardly-projecting bracket 5,

carried by the fixed member 1, said bracket being hollow to form a thread :box or receptacle and consisting of a floor 6 and end plates,

7, said movable jaw 3 beingmounted be tween, and hence laterally braced by, the sidewalls'7 of the thread-box. Also'the members of the vise are connected by an adjusting bolt 8, which may be fitted with any suitable means, such as a nut 9, for varying the position of the movable jaw 3 with relation to the p other member of the vise to clamp an object, such as parallel folds-or layers 10 and 11 of 'leather or analogous material, between the faces of the jaws and with the upper edge of s-uchlobjectprojecting beyond the contiguous edges of the jaws to provide for connecting the edges of the folds or layers by a row of stitching and 'the auxiliary or shuttle thread which is engaged with the loop of the main or needle thread during the projection of-the needlethrough the folds orlayers of material which are being united.

Extending rearwardlyfrom the fixed member of the vise, which constitutes a supporting-frame, are-arms-12, which are provided planes of the vise-jaws isa carriage or feed block 16, having a transverse or horizontal guide-opening 17, which snugly fits the feedbar 15, and also having a vertical guideopening 18, in which'is fitted for. axial movementthe spindle or stem 19 of a needle-bar-carrier 2 0,fsaid needle-bar carrier being provided at its upper'cnd with'a bowed yoke 21, having horizontally-Mined gn-ide openings 22 and 23 afor the needle-barf-24, said needle-bar being 1 11 n-te'da' in i=-thef guidegffor reciprocation t0- 5 rd andifrom'the'. planes of "tliegvise-jaws.

preferably consisting offa looped spring 33, attached at oneend to the-carriage 16 and having its itree arm-idisposed' to engage the I teeth of the rack and normally and yieldingly 'l heId in engagement therewith by theresilie'nee of the loop. Said p'awlor'yielding arm" 320i the-spring-loop is extended beyond its point of contact with the teeth of the rack to terma-trip-ar'm 34, which is arrangedd'nfthe pat/h ef the backward movement of a camface35, located upon the needle-bar near its irontend, saidncam-face forming one side of.

anenlargement or head of the needle-bar.

,'-.I'-he' abri1pt surfaces of the teeth of the rackbar facein the direction of feeding of the car- .friage, and'hence when the needle-bar is drawn rearwardly sufliciently to cause the engagemerit of its'oam-face with the triparm 34 said I pawl is held by the abrupt face of the engaged rack-"teeth from yielding, and hence the 'carriage is advanced in the desired or feeding directiomthe' backward movement of the needlebar being limited (to prevent disengagement of the cam-face from the trip-arm) by any suitable means, such as the eontact ofthe heador enlargement of the needle-bar with the front guide 22. To prevent excessive movement of the carriage-and yieldinglyhold the same after each advance movement, -I-employ a holding-' pawl 36,extending through a cut-away portion I orchannel'37 in the'front wall of the guide 17, I said helding pawl constituting one arm of a.

lecpedeprin g38,cerresponding, substantially, in construction with the spring 33. The holding-pawl indicates, by snapping into engagement with a succeeding tooth, when the 'car-' 'riage has been advanced one step, and hence the operatoh' is-n'otified by the-holding-pawl 'whena suc'ceedingadvance of the needle-bar '-may be inaugurated. The pawl 36 is also extended to form a releasing-arm 39, whichis "located above the upper side of the carriage and projects laterally in rear of the trip-' farm 34,- as clearly indicatedin Fig. 5.'- By s the holding pawl may be advanced to release .:'the ,rack teeth, and thelcontact' 'of said releasing-'arm'with the trip-arm 34 of the feedteeth, whereby the carriage maybe moved manually to the desired position upon the rack-bar. The rack-bar is held with one of its series of teeth in operative relation with the feed-pawl by means-of locking-keys,

otpins 40, arranged in the arms 12 and enthe rack-bar, and it will be understood that by removing these holding-pins the rack-bar may be turned in its hearings in said sup-, porting-arms to ar'range the desired series of rack teeth inoperative relation with the pawl .-,to insure the desired length of step during the feedingmovement,

The headof the needle-bar is provided with 42, and 'alsoa-n pawl-seat 43, in which is fitted an awl 44, the awl being preferably shorter than the needle and spaced therefrom a dis-'- 3Oand 31 of the rack-bar. The-coarse teeth 30 maybe equal to the in-ter-val'betweenfthe needle and awl. The holding-pawlserves to indicate to the operator during the irse of the rack-teeth-3l when the baclgward or,re-- tracting movement of the needle-bar should ceaseinorder tovobtain the short stepof the carriage desired in connection with fine or close work.- Also the head of the needle-bar is providedwith athread-guide 45,. through which extends the thread 46 to the eye of the needle 42, said needle-thread approaching the guide 45 through: the guide-slot 47, formed in the fixed jaw-2 of the vise'eand the reel-spool 48, from which said thread is supplied, being conveniently located in theth'read box 5 at the base of the movable or adjustable jaw 3 of said vise. In connection with this threadguide 45 is a tension-spring 49, operating in a groove 50 in the'side of the needle-bar-head thisjtension-spring is provided with arealwardly-extendin g trip-arm- 51,=-deflected outwardly at its rear end and adapted dnrifig the rearward movement of the needle-bar for engagement with ,a' trip 52, disposed in the vary itsposition forwardly and rearwardly with relation to the path of movement of the trip-arm, w-herebyt-he, release of the thread is adapted to' occur at different points in the a needle-seat 41, in which isfi'tted ane'edle to intersect said thread in the guide 45 and I lock the thread normally, against? movement through said "guide, said spring being prefen ably of looped construction, as shown. Also path thereof, said trip being adjustable to pressing 'forwardlyhpon said releasing-arm pawl- 32 will disengage the latter from the which in the construction illustrated consist gaging transverse seats in'the extremities of tance which is divisible evenly by the interval between the teeth of either "of said'series path of movement of theneedle-bar. In the construction illustrated said trip is pivotally- ,mounted, as at 53, uponth'e yoke 21 of the needle-bar carrier, and itis adapted to be engaged-with either of a plurality of seats 54,

located at different distances from the front end of the needle-bar, said-trip being preferably of yielding material,whereby it is adapted to be held by its inherent resilience in the-seat with which it is engaged, while allowing the manual displacement thereof from one seat in order to provide for its engagement with another when it is desired to vary the point of said article and carry with it the needle-- thread.- The needle bar is then slightly backed to provide for the engagement with the loop of the needle-thread by-an auxiliary or shuttle thread 55, such engagement being accomplished manually and being clearly in-- dicated in Fig. 7. The needle-bar is then fully retracted, and when the cam-face of its head comes in contact with the trip-arm of the feed pawl the carriage is advanced through an interval corresponding with that between two contiguous teeth of the engaged rack. Duringthe advance movement of the needle-bar the awl 44. passes through the material at an interval from the needle, and hence when the carriage has been advanced in the direction of feed preparatory for a second stitch the needle is brought opposite the puncture formed during the previous stroke by the awl, and hence the movement of the needle through the 'material is facilitated. During the backward 'stroke of the needle-bar the thread-tension remains in engagement with the needle-thread a sufli cient length of time to draw the auxiliary or shuttle thread into the opening which has been vacated by the needle, and it is obvious that by varying the position of the trip 52 the auxiliary or shuttle thread may be drawn a greater or less distance into the material which is being sewed to suit the thickness of the article.

When it is desired to vary the path of the needle-bar with relation to the, planes of the vise-jaw faces, or, in other words, tostitch obliquely through an article held by the visejaws, it is necessary simply to elevate the needle-bar carrier sufliciently to disengage the cross-head or pin 26 from the seat-25 and turn the carrier spindle or stem in the guide 18. Tilting movement of the carrier with relation to the supporting-frame is prevented by the engagement of the lower end of said spindle or stem witha guiding-keeper 56, suitably supported by the stationary member 1 of the vise. Also in order to provide'for interchanging and replacing theneedle and awl I employ means-for detachably securing the same in placegsaid means consisting of lation with the jaws of the vise.

tapered keys or fastening-pins 57, fitted in.

suitable seats intersecting the seats 41 and 43 and adapted when driven into place to bind frietionally against'the needle and awl to prevent longitudinaldisplacement thereof.

In the operation of the mechanism the extension of the upper edge. of the material above the jaws of the vise and the passage of the needle through this extended edge portion of the material, such as a harnessstrap or the equivalent thereof, is liable, except when'the material is particularly stiff or resistant, to bend the same, and thus interfere with the perpendicular traverse of the needle or the accurate penetration of the.

material perpendicular to the opposite surfaces thereof. Therefore I prefer to employ an auxiliary clamp 58, connected by a tension brace-rod 59 with the yoke 21, said brace-rod being pivotally connected to the yoke, as at 60, to adapt it to be swung upwardly to remove the auxiliary clamp from operative re- The clamp which I have illustrated in the drawings con: sists of a collar or shoulder 61, a threaded stem 62, which may be formed as a continuation of the brace-rod 59, and a nut 63, threaded upon said stem for adjustment toward and from the shoulder or collar 61, whereby the exposed or projecting upper edge ofthe material to be punctured by the needle may be arranged between the planes of the shoulder or collar 61 and the nut 63 and the latter adjusted to firmly clamp said edge, and thus hold the folds or layers of the object in contact, while the brace-rod prevents the bending or deflection of said edge by reason of the pressure of the needle and awl in passing therethrough. Also in practice I may, as shown in the drawings, form a yielding locking-arm 64, extending forwardly from the shoulder or collar 61 and having a straight bearing portion '05 to engage one side of the .nut 63 and hold the latter against loosening or unscrewing after it has reached the desired adjustment. Preferably the holder-arm (35 is looped rearwardly from its point of attachment to the clamp to provide the necessary resilience even when the nut 63 is adjusted close to the plane of the shoulder or collar (51.

In practice various changes in the form, proportion, and the minor details of construction may be resorted to without departing from-the spirit or sacrificing any of the advantages of this invention. l-Iaving described my invention, what I claim is 1. In a harness-machine, the combination of a vise, and means for varying the relative positions of the jaws thereof, one of the visejaws being provided parallel with its face with a guide-slot, of a carriage supported by one of the vise-jaws for movement parallel with the faces thereof, and a reciprocatory too needle-bar and operating devices mounted upon the carriage, the said slot in one of the vise-jaws forming a guide for the thread in its passage to. the needle ea iried by the nine.
